What Does Peptide Purity Mean? Complete Guide to HPLC, COAs and Research Peptide Quality

What Does Peptide Purity Mean? Peptide purity refers to the degree to which a peptide sample is free from contaminants and impurities. This reflects its quality and effectiveness for research purposes. This metric is often assessed through high-performance liquid chromatography (HPLC), which separates the components of the peptide mixture to determine purity levels. Certificates of […]
How to Read a Peptide COA: Complete Guide to Purity, HPLC, Mass Spectrometry and Research Peptide Testing

If you work with research peptides, knowing how to read a peptide COA is one of the most important parts of evaluating laboratory materials. A Certificate of Analysis, commonly shortened to COA, is a laboratory document containing analytical information about a particular sample or batch. Depending on the laboratory and the tests ordered, it may […]
